TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 414,095, dated October29, 1889.

Application filed July 26, 1888. Serial No. 281,101. (No model.)

To all whom t may concern.'

ABe it known that I, FRANZ X. WAGNER, a citizen of the United States,residing at New York, in the county and State of New York, have inventednew and useful Improvements in Type-Vritiug Machines, of which thetollowing is a specification.

My invention relates to improvements in typewritin g machines; and itconsists in cer tain novel features of construction, as fully set forthin the following specification and claims, and illustrated iu theaccompanying; drawings, in which-- Figure 1 represents a plan or topView of a type-writing machine constructed according to my invention, anumber of the keys and their connections being omitted. Fig. 1* is asectional View of a detail part. Fig. 2 is a vertical section in theplane .fr at, Fig. 1. Fig. 3 is a similar section in the plane y y,Fig. 1. Fig. 4. is a vertical section in the plane ,e e, Fig. 2. Fig. 5is a section in the same plane as Fig. 4, showing the parts in adifferent position. Fig. 6 is a plan or top view of the ribbon-actuatingmechanism. Fig. 7 is a vertical section in the plane m, Fig. 1. Fig. Sis a vertical section in the plane y y', Fig. 1, certain parts of therear of said section being omitted. Fig. 9 is a vertical section intheplanez e', Fig. 1. Fig. 10 is a vertical section in the plane 902m?,Fig. 1. Fig. 11 is a front view of one of the typecarriers, thetype-bars being omitted. Fig. 12 is a rear view of the same providedwith the type-bars. Fig. 13 is a vertical section in the plane y2 y2,Fig. 12.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates a Vbase-plate or bed, uponwhich are supported the operating parts of the machine.

B, Figs. 1, 2, and 3, is the platen, which is mounted in a suitablecarriage that can be swung abouta pivot-bar a at the rear of thebase-plate or bed. The platen is supported from below by a roller l),Figs. 2 and 3, which travels upon ahorizontal guide-bar c, secured tothe base-plate or bed. Suitable devices for clamping the paper to theplaten and means for rotating the platen are provided, as usual. Infront of the platen B are secured a pair of parallel guides C C', intowhich is fitted a typecarrier D, which can freely move in a right linebetween said guides. In the example illustrated in the drawings, Figs.3, 4, 5, 11, 12, and 13, the type-carrier consists of a iiat metallicframe the top and bottom of which have extensions entering grooves int-he guides O C', and the type-bars E are secured to the lower portion,of the frame and can swing freely about their iixed ends in a plane atright angles to the plane of the carrier, Fig. 13. The type-bars may beconveniently made thin and of resilient materialmi such as steel-audaffixed directly to the earrier by rivets or otherwise; or they may bemade thick enough so as not to bend and be pivoted to the carrier,suitable springs being used to return and hold them in their normalposition against a suitable cross-bar or stop on the carrier. To obtainthe impression of any desired type, the type-carrier is moved in itsguides so as to bring the said type in the correct position in line witha hammer, to be hereinafter described, and then the type-bar is pressedforward to produce the impression.

In the drawings each type-bar is shown provided with two types, onearranged above the other, and consequently to bring either of the sameinto the printing-line the carrier must be moved in a vertical plane.

The keys F F and G G, Figs. 1, 2, and 8, all have suitable guides in thebase-plate or bed A, or in the key-board A', and are held in theirnormal or elevated position by suitable springs. By the depression ofthe key F or the key F the type-carrier is moved to bring thecorresponding type-bar to its correct position, and the type-carrier Dis lowered to bring the upper type into the printingline, and, finally,the typebar is vibrated to produce the impressionl G G' is depressed,the type-carrier is moved to bring the same type-bar into the properposition, and the carrier D is raised, so as to bring the lower typeinto the printing-line. The keys F are arranged in series of two each,as F G and F G', throughout the dimensions of the key-board, the saidkeys being arranged approximately opposite each other, Fig. 1.

The above-described effects are produced as follows: Each of theopposite keys, as F G, is provided with acam f g, Figs. 2 and 8, whichcams face in opposite directions and engage If one of the keys IOO witha rod H when the corresponding keyis depressed. rThe main key-rod Hextends horizontally across the length of the keyboard and is affixed tothe ends of two vertical arms h h, Figs. l and 2, pivoted to lugs risingfrom the base-plate or bed. A second or supplementary key-rod H issimilarly mounted in arms h and extends between the set of keys F and G.If more sets of keys-are used, additional key rods are provided. Therods H and H are connected by a link H2, Fig. 3 especially, so that wheneither rod is moved by the depression of a key the other rod Will bemoved simultaneously therewiththat is to say, the rod H will be movedWhenever a Ikey is depressed. The rod H, Figs. 3

and El,engages with the upper end of =a lever 1 vl, which is pivoted ona line with the ,pivots f of the arms h, and the free end `of said leverengages a slide I, located beneath the baseplate orb'ed. I n the endofthe-slide is formed 'Aan/oblique slot i', which engages with a ro'd 1'.,Figs. 4,5, 8,-and 10. The rod I is mounted in `a lever Evframe i2,swinging abcut pivots t3, g so thaftwhen the slide I'is moved in thedirecg tionof arrow l, Fig. 8, 'the rodis moved downf ward, Aand whenthe slide is moved in the opy "is used, (see Figs. 2, 3, 1i, 5, fand711-)v -Afslide posi/te direction the rod is moved upward.

The guides C C for the type-carrier D are both connected by rigid linksJ J" with 'the lever-frame m3 and consequent-ly participate in the upanddown movements of the rod l, whereby the types upon` `the type-'bars'are adjusted, as previously described. spring `I2, 3, 4acting on therod I through an intermediate arm rigidly secured tothe said rod, laidsin returning the carrie'rguides to.`

g, Referring to Fig. 2, each of the keys F" and G is providedfwith a toejjQboth of whichE engage with a bent arm 7c K, located beneath 4thekey-board. 'This arm 71: K is pivoted at 7c" lto a'n arm K having apivot at 7a2 on a lug projecting from the bottom of the base-plate ,orbed. leveiI L, which can turn about a pivot Z, secured 4in thekey-board.

Ili-ssdistance from 'thepivot m0 the levers M M* will 'be vi'bratcd`through a 4less or greater 'distance and the type-carrier D will bemoved 'lo the arm k K is attached at Z a The socket m inthe slide Nengagea with j'a pin n in the carrier D, so that the car'I frier, Fig.42, -participates in the 4movements ofi through a correspondingdistance. The same effect could be produced by giving a greater or lesspitchto the cams L. In the standard A2 are formed bearings for a hammerO, which is engaged by a bell-crank lever O, Figs. 2 and 3, pivoted at oin said standard. The free end of said lever is engaged by a lever O2,Fig. 3, pivoted at o to the key-board and provided at its outer end withtwo converging cam-faces o2 02, which are engaged by the shaft H, sothat when the latter is vibrated in either direction by the depressionof akey the lev'e'r O2-is oscillated to actuate the hamm'e'r to move atype which has been brought in line with the hammer against the platen.In the type-writing machine illustrated in the drawings I have provideda second or supplementary type-carrier D containing-additional types,which carrier vcan -becaused to take the place o'f the lcarrier D. By'this means the jcarriers can be 'e'ach provided with a less number oftypes, and consequently a long movement of the carriers for adjustingthe ty-.pe 4'to -thfe proper .position is not necessary Y Y v Forreplacing the carrier D by 't-*li'ecarrier D', and vice versa, thefollowing mechanism P, having bearinfgsin stationary posts Q9 andpit-carries Va -rac'k P', which is @engaged byja toothed segmentP'mounited -o'n 0a rock-shaft p".V On theopposite endfof 'the rockfshaftis rigidly lmounted va toothedsegment p2, which. fis V.erjrgaged by `arack p3, having theattached headl p4. A vsprin-gl, in conjunction lvvithsttitahle stops, holdsfthe parts -norlnallyin the position shown `inFig. 4. IIffV the headI is depressed, 'the slide is moved to occupy theposition shown 1in Fig. 5. Oppositeandin-close proximity to theslide Pfis la slide Q, Figs. il, '3, and 9, which has 'a pin q and slot qconnectionwith'the former. (See Fig. 9.) This slide Q is also supportedin sockets in the posts p 4and pif, and is Aprovided W'ith'sockets q2g2, Figs. 2, 3, Ll, 5, and 9, which are `normally out ofengagement withprojections'or pins d d 'on thevcarriers; but when the slide Q is movedthe guides C C for the carriers are moved laterally toward the slide,and the projections l d engage with the sockets, so that the carriers DD are moved with the slide to bring the-same in the position shown yinFig. '5. This 4lateral movement 'of 4the ygnidesfC C" toward the slide1Q Vcan be .produced by `the action of an arm yfR, which 1is pivoted atr tothe post jo and engages with the lower guide. On the slide P are twowedge-shapedcams o3 o, which engage in the movement of the slide with 'alinger r of the arm R, so `as `to force the arm to turn about I. itsypivot fr to draw'theguides OC towardthe 4A cam-'lever L, a bent armkK,*and arm K E are provided for each key of the keyboard..- -Byarranging the cam-levers L at agreater ori slideQ. An'intermediatefingerWon theiarm R passes 'through the slot rs nthe slide y'Q when the'arm isYvibrated ,land on ihesubsequent movement of said slide Q locks the arm4in its :assumedpositioniduring the movement of said slide. The cam osactuates the arm IOO IIO

R when the slide moves in one direction and the cam oi when it moves inthe opposite direction. The object of having the pin q and slot qconnection between the slides P and Q is to permit the slide P to bemoved sufficiently to cause the arm R to be vibrated, so as to move theprojections CZ eZ on the carriers well into the sockets q2 q2 in theslide Q before said slide Q is set in motion. To lock the carrier D whenidle, Fig. 4t, a small proj ection Z2 is formed thereon, which engageswith a recess (Z3, Fig. 5, formed in the standard A2. The projection Z2is withdrawn from the recess when the guides C C are moved laterally, asbefore described. A similar proj ection CZ4 and recess (Z5 are providedto lock the carrier D in its idle position, Figs. t and 5. The carrier Dwhen in its operative position is brought under the influence of thesame mechanism which has been described for actuating the carrier D.

For guiding each type accurately to its printing' position--that is, inline with the hammer-each cam-leverL has on its free end a cavity Z2,Fig. l0, which engages with a pin Z3 on the slide N. The levers L are soarranged that the pin Z3 is brought directly opposite the said lever,striking against a heel Z4 on the same whenever the corresponding key isdepressed, Figs. 2 and I0. The heels Z4 are guided in guides Z5 on thekey-board, Figs. l and 2, and are cut away at the portions nearest theslidegN, (see Fig. 2,) so that the pin Z3 can pass them when notdepressed by the key.

For letter-spacing, Figs. 2, 3, and 6, the platen-carriage is providedwith a pendent rack S, the teeth of which are engaged by a dog S',pivoted at s to the end of a slide S2 andcapable of turning in ahorizontal plane, Figs. 3 and G. A spring s', act-ing on the dog S, hasatendency to turn the same about its pivot; but normally the free end ofthe dog is in contact with a stationary cam s2, Fig. 6, which holds itin line with the slide S2. The slide S2 is guided by suitable means ateach end and is engaged by a rod extending across a pair of bell-cranklevers Sa S3, Figs. l, 2, and 3, the opposite arms of which are unitedby a rod which is engaged by the lever O2, which actuates the hammer,the vibration of which lever imparts a reciprocating movement to theslide S2. Vhen the slide S2 is moved in the direction of arrow 2, Figs.2 and 6, the dog S is released from the cam 82 and turns about its pivotin the direction of arrow 3, Fig. G. On the return of the slide the dogengages with a new tooth and is turned to its original position bycontact with the cam s2, whereby the carriage is advanced. To preventany lost motion between the dog and the teeth of the rack, the body ofthe former is made Somewhat tapering, so that it iills up completely thespace between two consecutive teeth.

For feeding the ribbon (not shown) the vertical spindles t t of thespools T T are provided with toothed wheels t2 Z2, (see Fig. 6especially,) into contact with which can be thrown the feed-pawls u u,which are mounted on levers U U', having pivots u2 ug, secured in acarrier U2, which can be moved in the direction of its length, so as tothrow the pawls u into contact with the toothed wheel t2 or the pawl uinto contact with the toothed wheel t3, so as to feed the ribbon ineither direction. The carrier may also be left in an intermediateposition, so that both pawls are out of action. The ends of the levers UU are united by a common pin a4, which engages with a slot M5 in theslide S2 of the carriagefeeding mechanism, so that when said slide isactuated the levers U U are vibrated about their pivots a4 a5 to actuatethe pawls. In order that the spools T and T can be vertically adjusted,so as to be able to make use of the complete width of the ribbon as itbecomes worn out, I feather the same to the spindles t t', and the yokes,t5 t6, embracing the spools, are engaged by arms V V, Figs. l, 2, and3, secured to a common rock-shaft V2, having bearings on the key-board.A springhandle c, attached to the rock-shaft and provided with a nib o',engaging notches v2 in the base-plate, Fig. 1*, is used to actuate therock-shaft and to secure the same in position when adjusted.

What I claim as new, and desire to secure by Letters Patent, is

l, The combination, with a type carrier movable in a right line, of thelever system M M,'the cam-levers L L', engaging said lever system, aconnection between the lever system and the type-carrier, and a key foreach cam-lever, whereby the depression of a key actuates thetype-carrier, substantially as shown and described.

2. The combination, with atype-carrier containing two or more rows oftype, of a main key-rod connected with the carrier, as de scribed, and asecondary key-rod connected with the main rod, and keys engaging withsaid rods, whereby the movement of the secondary key-rod is conveyed tothe main rod, substantially as described.

3. The combination, with a carrier containing two or more rows of type,of guides C C', for guiding the carrier in a rectilinear path, the armsJ J ,and the lever-frame 2, supporting said guides, a rod H, carried bypivoted arms 7L, keys F G, &c., provided with camfaces f and g,respectively, the lever i, and slide I, provided with inclined slotengaging a rod on the lever-frame z2, substantially as shown anddescribed.

4. The combination, with a carrier provided with movable types andguided to move in a right line, of a hammer guided in bearings at rightangles to the carrier, the key-rod I-I, a lever O', engaging saidhammer, and a lever O2, having canrsurfaces 02 o2, engaging with thekey-rod and with the lever O, substantially as shown and described.

5. The combination, with the type-carriers IOO D D and the guides C Cfor the same, of the slides P and Q, the shifter R, engaging the -C C, atype-carrier fitted to said guides to i'nove in a right line thereuponand having a series of type-bars, each containing two types,

and twosets of keys F and G, and connections, substantially asdescribed, for respectively moving the type-carrier back wand forth in aright line on the guides and lowering and raising the same to bring theupperand lower rows of type into the printing-line.

In testimony whereof I have hereunto set my hand and seal in thepresence of two subscribn ing witnesses. v
